Objective

The participant will understand the statistical principles necessary for process control, will be able to interpret any control chart and capacity study (Cp, Cpk), and will understand the importance of decision making based on data.

Participant’s Profile

Professionals from engineering, quality control, incoming inspection and production areas , as well as all personnel involved in process control, product characteristics control or data analysis for decision making.
